Analog Devices’ 16-Channel, 12/16-Bit Digital-to-Analog Converters Target Telecom Optical-Module Control

Analog Devices, Inc. announced today a pair of highly integrated 16-channel digital-to-analog (D/A) converters that significantly reduce the system footprint for wired telecommunications systems, yet without any performance compromise.

The 12-bit AD5767 and 16-bit AD5766 are fully integrated devices with all the required bias ranges for coherent optical systems of medium- to long-haul, fiber-based telecommunication deployments. Both ICs integrate a wide array of discrete components to provide the required voltage ranges and additional system functionality in a very small area. These D/A converters are well-suited for optical modules and electro-optical functions such as bias control, including Mach-Zehnder modulator-bias control.

The converters are available in both space-saving 4 × 4 mm WLCSP and a 6 × 6 mm LFCSP packages. They provide a range of unipolar or bipolar output voltages from the user-supplied 2.5-V reference; these outputs can be adjusted down to −20 V or as high as +14 V. The output buffers can sink or source up to 20 mA, and the D/A converter can impose low-frequency dithering on these outputs if needed, thus eliminating the need for external circuitry. An integrated output multiplexer allows each of the 16 channels to be monitored, if desired.

The pin- and footprint-compatible AD5766 is functionally identical to the AD5767, but with 16-bit performance for applications which require the additional resolution. The AD5767 and AD5766 use a versatile 4-wire serial interface that operates at clock rates of up to 50 MHz for write mode, and which is compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™, and DSP interface standards. These ICs operate over the -40 °C to +105 °C range for additional versatility.
